.SH "DESCRIPTION"
.sp
For the NVMe device given, send a Vendor Unique WDC vs\-smart\-add\-log command and provide the additional smart log\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1)\&.
.sp
This will only work on WDC devices supporting this feature\&. Results for any other device are undefined\&.
.sp
On success it returns 0, error code otherwise\&.
.SH "OPTIONS"
.PP
\-i <NUM>, \-\-interval=<NUM>
.RS 4
Return the statistics from specific interval, defaults to 14\&. This parameter is only valid for the 0xC1 log page and ignored for all other log pages\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR, or
\fIjson\fR\&. Only one output format can be used at a time\&. Default is normal\&.
.RE
.PP
\-l <NUM>, \-\-log\-page\-version=<NUM>
.RS 4
Log Page Version: 0 = vendor, 1 = WDC\&. This parameter is only valid for the 0xC0 log page and ignored for all other log pages\&.
.RE
.PP
\-p <LIST>, \-\-log\-page\-mask=<LIST>
.RS 4
Supply a comma separated list of desired log pages to display\&. The possible values are 0xc0, 0xc1, 0xca, 0xd0\&. Note: Not all pages are supported on all drives\&. The default is to display all supported log pages\&.
.RE
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
Sets the command\(cqs nsid value to the given nsid\&. Defaults to 0xffffffff if not given\&. This option may not affect anything depending on the log page, which may or may not be specific to a namespace\&.
